"We were 100% satisfied with Fresh Air Heating & Cooling and would HIGHLY RECOMMEND them. Everything about the entire experience was fantastic. Short story is our heat went out on a morning when the temp was minus 6 degrees. They were able to repair the system that day and install a new one later that week. There was no high pressure sales pitch -- only excellent advice and service. We found Fresh Air Heating & Cooling on Angie's List and are now LOYAL CUSTOMERS!"

"I needed to replace my parents' 40 year old AC Condenser and coil, and replace it with something that worked with the new furnace my father got installed four years prior. They were able to do the work requested, and also offered to redo the furance installation as the previous company installed it right on the basement floor where any backup/water could possibly get into the system. They were very prompt and showed up on time/on schedule. They were very upfront about costs and pricing and there were no last-minute price changes or hidden fees, which I appreciate. Work was done well and they ensured that everything worked before leaving the job site. The gentlemen working were very professional and understanding. I highly recommend them for anyone looking to replace their HVAC or to correct work that was previously poorly done."

I have had them out to service the system twice a year and the scheduling to do so is easy and the service has been excellent. AAA home services has always communicated well and I have had them do exceptional plumbing work including the installation of a hot water heater. Thank you AAA home services."

FAQs for central a/c service or repair projects in Wentzville, MO

Coils work to absorb heat into the refrigerant that flows through them, moving heat from one location to another. For air conditioning, the evaporator coil inside the air handler in your home absorbs heat. It then transfers the heat outside to the condenser coil, where it releases it. The opposite process happens for heat pumps. When the coils get dusty and dirty, it reduces how well these components work.

Skip regular cleanings, and dirt, debris, and mineral deposits will blanket your evaporator and condenser coils. When that happens, the coils can’t shed heat efficiently, so the system works harder and your energy bill climbs. Over time, overheating strains the compressor and can trigger a full breakdown—an avoidable repair that often costs far more than a simple annual cleaning.

AC coil cleaning is an investment that pays for itself in the benefits it provides. Dust‑caked coils force your AC to run longer, so you spend more on electricity and rack up extra wear. A quick professional cleaning restores efficiency, trims monthly bills, and eases strain on expensive parts. Over the long haul, that small yearly fee delays pricy repairs and stretches the unit’s lifespan, making coil cleaning one of the smartest HVAC tune‑ups you can schedule.

Watch for higher electric bills, rooms that stay warm no matter how low you set the thermostat, or an AC system that runs nonstop. Extra humidity and frost on the coils are also red flags. Catching these clues early lets you schedule a quick cleaning before the system overworks itself and triggers an expensive breakdown.

Your AC cleaning technician starts by shutting off the power to the unit and removing the faceplate. Compressed air and a vacuum hose blast away loose debris, followed by a coil-safe, no-rinse cleaner that dissolves stubborn grime. After the solution has soaked in, the professional wipes the fins, reassembles the housing, and restores power, leaving the system ready to cool at peak efficiency.
